Electricity prices in Slovakia
What a household in Slovakia pays for electricity, where the power comes from, and how the country differs from its neighbours.
More than half of Slovakia's electricity comes from nuclear reactors, a larger share than in any other EU country except France. Two sites, Bohunice in the west and Mochovce in the south, run around the clock, while dams on the Danube and the Váh add flexible hydropower. Slovakia pays for its power in euros, which makes its bills easy to compare with Austria's or Germany's.
What households pay is not left to the market alone. The network regulator ÚRSO caps the price that suppliers may charge homes, and in recent years the state has added its own measures to keep bills down.
This page therefore shows Slovakia's official household prices from Eurostat rather than an hourly exchange price.
The exchange's hourly prices in Slovakia may not be freely republished, so this page does not show them. The household prices here are Eurostat's official figures, updated every six months.

How the electricity price works in Slovakia
Market coupling, OKTE and a price ceiling for homes
Slovakia is one bidding zone. Its day-ahead price is set by OKTE, the short-term market operator, in the European market coupling, where Slovakia is calculated together with Czechia, Hungary and the rest of the EU. SEPS runs the transmission grid; three regional companies in the west, centre and east of the country handle distribution.
Households are treated differently from businesses. ÚRSO, the Regulatory Office for Network Industries, sets maximum prices for supplying electricity to homes as well as the network tariffs. During the energy crisis the government also struck an agreement with Slovenské elektrárne, the largest generator, to sell power for households at a reduced price, which kept retail prices far below the wholesale peaks.
Supply, distribution and the nuclear fund
A Slovak bill combines the supply of electricity with a distribution charge, which has a fixed monthly part depending on the main circuit breaker and a part per kWh. On top come a charge for network losses, a tariff for running the system, which funds support for renewables and combined heat and power, and a tariff for system services that keep the grid stable.
A further levy goes to the National Nuclear Fund, which pays for decommissioning reactors and storing spent fuel. VAT is added at the end. Homes with electric heating or heat pumps can choose two-rate tariffs with cheaper hours.
Reactor availability, the Danube and the neighbours' prices
With so much nuclear power, the state of the reactors is the first thing that moves the Slovak price: a refuelling outage at Mochovce or Bohunice leaves the country more dependent on imports. River flow comes next, since a dry year cuts output from the Danube and Váh plants.
Because the market is coupled, the Slovak price also tracks what happens in Czechia and Hungary. In practice it often sits between the two: when Hungarian evenings turn expensive after the sun sets, Slovak lines to the south fill up and the price rises with them. Gas plants set the price in the tightest hours.
Nuclear first, then rivers
The four units at Bohunice and Mochovce were joined by a third Mochovce unit in 2023, which lifted output enough to make Slovakia largely self-sufficient over the year. Hydropower comes from the Gabčíkovo plant on the Danube, a cascade of dams along the Váh and the pumped-storage plant at Čierny Váh, which stores energy for peak hours.
Coal has almost disappeared: the lignite-fired plant at Nováky, which burned local coal for decades, closed at the end of 2023. Gas and biomass fill much of the rest. Solar is growing slowly, and Slovakia has practically no wind farms, which sets it apart from most of Europe.
Between Czechia, Hungary and Austria
Czechia, Slovakia's former partner in one country and one grid, combines nuclear with lignite, so its price is more exposed to carbon costs. Hungary to the south imports a large share of its power and is often more expensive in the evening. Poland to the north still burns mostly coal.
Austria, right on Bratislava's doorstep, has the hydropower of the Alps and a fast-growing fleet of wind turbines – the very resource that Slovakia, despite a similar landscape in the west, has hardly used.
Slovakia compared with its neighbours
In 2024, nuclear made 62%, hydro made 15% and gas made 10% of the electricity generated in Slovakia. Wind, solar, hydro, nuclear and bioenergy together made 84% of generation in Slovakia.

Questions about the electricity price in Slovakia
- What does an ordinary household in Slovakia pay for electricity?
- A household in Slovakia using 2,500–5,000 kWh a year paid 19.9 c/kWh per kWh on average, all-in, in H1 2026, according to Eurostat. The price varies with the network company and the contract.
- How much of the electricity in Slovakia comes from nuclear?
- 62% of the electricity generated in Slovakia came from nuclear in 2024 (Eurostat), the largest single source.
- How does the power mix in Slovakia compare with the neighbours?
- In 2024: Slovakia: nuclear 62%, hydro 15%; Czechia: nuclear 41%, coal, lignite and peat 36%; Hungary: nuclear 42%, solar 24%; Poland: coal, lignite and peat 55%, wind 15%; Austria: hydro 53%, wind 12%.
- Why does this page not show hourly electricity prices for Slovakia?
- Slovakia's day-ahead price is published by the market operator OKTE, and it is not clear that those figures may be freely republished. Rather than risk that, the page shows Eurostat's official household prices for Slovakia, which are free to use and include taxes and network charges.
- Is the household electricity price regulated in Slovakia?
- Yes. The regulator ÚRSO sets a maximum price that suppliers may charge households for the electricity itself, and it also sets the distribution tariffs. Businesses buy at market prices. In recent years the state has added temporary support to keep household bills lower.
- What is Gabčíkovo?
- Slovakia's largest hydropower plant, on a canal of the Danube downstream of Bratislava. It was planned under a 1977 treaty between Czechoslovakia and Hungary as part of a joint scheme; Hungary later withdrew from its part, and the dispute went to the International Court of Justice.
